Definitions

  • the present disclosure relates soil repellent compositions for treating fibrous substrates, methods of making, and the like.
  • Stain and soil repellent chemicals are often applied during the production of fibrous substrates including carpets and textile products used for upholstery, bedding, and other textiles.
  • Anti-soil treatments of such fibrous substrates have primarily been based on variations of highly fluorinated polymers which, among other effects, tend to reduce the surface energy of the fibers resulting in a decrease in the soiling of the fibrous substrates.
  • a considerable disadvantage of such fluorinated polymers is their high cost.
  • Non-fluorinated polymers have also been developed to treat fibrous substrates, especially carpets, to reduce soiling. Examples include silicones, silicates, and certain silsesquioxanes. However, these non-fluorinated compositions generally do not provide the same soil repellent effect on fibrous substrates compared to the fluorinated polymers.
  • a satisfactory handle, including smooth interactions between carpet fibers, is especially important for fibrous substrates such as carpets and textile products used for upholstery, bedding, and other interior applications. Increased value-in-use is associated with a luxurious tactile sensation that is preferred and desirable for these fibrous substrates.
  • non-fluoropolymer topically-applied agents have been problematic because such agents tend to cause increased soiling and they generally wear or wash off quickly, rapidly losing their tactile effectiveness.
  • a new low cost composition is needed for treating fibrous substrates not only having the soil repellent effect but also maintaining a smooth and high- quality handle.
  • Embodiments of the present disclosure include soil repellent compositions, methods for imparting resistance to soiling on a fibrous substrate, fibrous substrates to which a soil repellent composition has been applied and dried, methods of making soil repellent compositions, and the like.
  • One exemplary soil repellent composition imparting soil resistance on a fibrous substrate includes: a water-based mixture of: a fluorochemical, a silsesquioxane-containing sol, and a lubricity-enhancing agent.
  • One exemplary method for imparting resistance to soiling on a fibrous substrate includes: contacting the fibrous substrate with a soil repellent composition followed by drying, the soil repellent composition comprising a water-based mixture of: a fluorochemical, a silsesquioxane-containing sol, and a lubricity-enhancing agent.
  • One exemplary fibrous substrate includes: a fibrous substrate to which a soil repellent composition has been applied and dried, where the soil repellent composition includes a water-based mixture of: a fluorochemical, a silsesquioxane-containing sol, and a lubricity-enhancing agent.
  • One exemplary method for imparting resistance to soiling on a fibrous substrate includes: (a) mixing a fluorochemical and a silsesquioxane-containing sol to form a blend; (b) treating the fibrous substrate with the blend; (c) applying a lubricity-enhancing agent to the treated fibrous substrate; and (d) drying.
  • One exemplary method for imparting resistance to soiling on a fibrous substrate includes: (a) mixing a fluorochemical and a lubricity- enhancing agent to form a blend; (b) treating the fibrous substrate with the blend; (c) applying a silsesquioxane-containing sol to the treated fibrous substrate; and (d) drying.
  • One exemplary method for imparting resistance to soiling on a fibrous substrate includes: (a) treating the fibrous substrate with a fluorochemical, (b) mixing a silsesquioxane-containing sol and a lubricity-enhancing agent to form a blend; (c) applying the blend to said fibrous substrate from step (a); and (d) drying.
  • One exemplary method for imparting resistance to soiling on a fibrous substrate includes: (a) contacting the fibrous substrate with a fluorochemical; (b) treating the fibrous substrate from step (a) with a silsesquioxane- containing sol; (c) applying a lubricity-enhancing agent to the fibrous substrate from step (b); and (d) drying.
  • Embodiments of the present disclosure will employ, unless otherwise indicated, techniques of synthetic organic chemistry, fabrics, textiles, and the like, which are within the skill of the art.
  • fiber refers to filamentous material that can be used in fabric and yarn as well as textile fabrication. One or more fibers can be used to produce a fabric or yarn. The yarn can be fully drawn or textured according to methods known in the art.
  • fibrous substrate includes, but is not limited to, textiles, carpets, apparel, furniture coverings, drapes, upholstery, bedding, automotive seat covers, and the like, that include fibers or yarns.
  • the term "carpet” may refer to a structure including a primary backing having a yarn tufted through the primary backing.
  • the underside of the primary backing can include one or more layers of material (e.g., coating layer, a secondary backing, and the like) to cover the backstitches of the yarn.
  • the term "primary backing” and/or the “secondary backing layer” may refer to woven or non-woven materials.
  • the woven materials may be natural materials or synthetic materials.
  • the woven materials can include, but are not limited to, cotton, rayon, jute, wool, polyolefins (e.g., polypropylene and polyethylene), polyester, and/or polyamide.
  • the non-woven materials can include fibers such as, but not limited to, polypropylene, rayon, polyethylene, polyester, polyamide, and combinations thereof, blends thereof, and the like.
  • backing refers to the primary backing, secondary backing, coating layer, combinations thereof, and the like.
  • lubricity refers to the capacity for reducing friction or the ability to lubricate (e.g., make more slippery or smoother).
  • sol refers to a colloid that has a continuous liquid phase in which a solid is suspended in a liquid.
  • Embodiments of the present disclosure include soil repellent compositions, methods for imparting resistance to soiling on a fibrous substrate, fibrous substrates to which a soil repellent composition has been applied and dried, methods of making soil repellent compositions, and the like.
  • Embodiments of the present disclosure include soil repellent compositions that include at least two of or all three of: a fluorochemical, a silsesquioxane-containing sol, and a lubricity-enhancing agent.
  • Embodiments of the soil repellent composition can be used to impart soil resistance to a fibrous substrate.
  • embodiments of the present disclosure include fibrous substrates to which a soil repellent composition has been applied and/or dried.
  • Embodiments of the present disclosure include methods for imparting resistance to soiling on a fibrous substrate.
  • the method includes contacting the fibrous substrate with a soil repellent composition followed by drying.
  • Embodiments of the present disclosure include methods for imparting resistance to soiling on a fibrous substrate.
  • the method includes the steps of: mixing a fluorochemical and a silsesquioxane-containing sol to form a blend; treating the fibrous substrate with the blend; applying a lubricity- enhancing agent to the treated fibrous substrate; and drying.
  • the steps are performed sequentially.
  • the method includes the steps of: mixing a fluorochemical and a lubricity-enhancing agent to form a blend; treating the fibrous substrate with the blend; applying a silsesquioxane-containing sol to the treated fibrous substrate; and drying. In an embodiment, the steps are performed sequentially.
  • the method includes the steps of: (a) treating the fibrous substrate with a fluorochemical; (b) mixing a silsesquioxane- containing sol and a lubricity-enhancing agent to form a blend; (c) applying the blend to the fibrous substrate from step (a); and (d) drying.
  • the steps are performed sequentially.
  • the method includes the steps of: a) contacting the fibrous substrate with a fluorochemical; (b) treating the fibrous substrate from step (a) with a silsesquioxane-containing sol; (c) applying a lubricity- enhancing agent to the fibrous substrate from step (b); and (d) drying.
  • the steps are performed sequentially.
  • Certain anti-soil compositions can adversely affect the hand of various textiles, especially when other chemistries, such as stain resists are also applied. It has been found that a small amount of a suitable lubricity-enhancing agent, when co-applied with an anti-soil treatment composition specifically including a fluorinated polymer and a silsesquioxane-containing sol can restore the smooth feel and overall handle of fibrous substrates without compromising the soil resistance imparted by the overall composition. Surprisingly small quantities of lubricity-enhancing agent provide the greatest benefit when compared to the application rates typical for similar materials. Even more surprisingly, when applied to carpet, the durability of the improved hand imparted by the minor lubricity-enhancing component is similar to that of the other substrates throughout the wear life of the carpet.
  • a surprising aspect of the present disclosure can be expressed in terms of other processes which are known to affect textile hand.
  • a large quantity of the agent is usually applied to create the desired hand.
  • 2% to 10% on weight of fiber (owf) or on weight of goods (owg), or more, of such agents (including the water in which they are generally received) is typically applied, as recommended by the manufacturers of the respective agents.
  • embodiments of the present disclosure include the application of about 0.01 % up to less than about 1.0% owf of a lubricity-enhancing agent by weight of the solution/dispersion/emulsion including water.
